NOCO Boost GB20: 500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack, Portable Jump Box, Power Bank & Jumper Cables - for 4.0L Gas Engines

I’ve used the NOCO Boost GB20 twice now, and both times it saved me from what could’ve been costly and time-consuming situations. Instead of calling a tow truck or waiting around for someone with jumper cables, I was back on the road in minutes. It's incredibly easy to use—even if you're not mechanically inclined—and it holds a charge for a surprisingly long time. I charged it once and it sat in my car for weeks before I even needed it, and it still worked perfectly. Recharging it is quick and hassle-free.This jump starter has already saved me money and time, and it’s given me peace of mind knowing I have a reliable backup in my glove box. If you drive a gas vehicle (up to 4.0L), I highly recommend this. It’s compact, powerful, and an absolute must-have!

was recommended by a friend and am super happy with this purchase. in the last 20 months, it has been a champ in helping start two riding mowers and a small truck. compact, easy to use, and very reliable for a great price. i've recommended it to another friend who also raves about it.

Haven't had a chance to use it yet and I hope I don't have to but I am quite sure it will start my Harley if the battery goes dead. It's charging capability is great and the power and the fact it is portable and it's functionality by plugging directly in to my NOCO battery tender port are really great ideas that the company came up with and I strongly suggest buying one if you don't already have one. You don't want to be on the side of the road you want to be riding.

Must have. This small charger jumps off pretty much any thing with a battery. I’ve used it to jump start my Ford F150 with ease. It’s small and stores easily just about anywhere and is easy to charge. Comes with a LED light built into the charger. I recommend this product. Why did you pick this product vs others?:Other recommendations and I have owned one before.

Love, Love and Love some more. Works perfectly and got me out of a couple of jams and helped neighbors with it.

The product does work and works good. No issues jump starting a CAN AM Spyder F3 LTD. Very easy to use. The only reason giving it 4 starts vice 5 starts is that the unit's battery does not retain its charge. You almost need to charge the unit weekly or at least check the status. I left the unit unattended for two weeks (no use, no need) but it was almost drained. Compare that with my portable air compressor that retains its charge for weeks on end. If you can remember to check the battery status at least weekly, then it's a good buy. You just don't want to be caught off guard needing it either for yourself or another person in need, and the unit is dead because it's been a week since you last charged it.

Charges fast and last a long time on the charge

I've jump-started my car maybe 6 - 8 times on a single charge with this battery pack, which I leave in my car full-time, all year long.I have a little-used car and the internal battery runs down so far nothing works at all. I need to use the "override" feature nearly every time (which is not well-documented, I have to keep going back to their web site to remind myself how it works) but once the pack is geared up and ready to go, my car alarm starts wailing and I can start it on the first try. No chugging or waiting for anything to "get more power" or whatever.I was initially worried about which exact model to purchase (NOCO makes a variety of battery packs for different loads; I had borrowed a friend's much more powerful GB150 which is 3000A versus this 500A pack), but this one works perfectly fine for my manual 4-cylinder car. We'll see if the "20 jump-starts per charge" is real, but even getting half that would be impressive.The connector wires couldn't be simpler: there is only one way to connect to the battery pack, you match red-to-red and black-to-black on the battery and go for it. The jaws are not as substantial as a regular set of jumper cables, but they seem both sturdy and appropriately "springy". I don't anticipate having to replace them any time soon. Fortunately, NOCO actually sells replacement wires, though they are fairly expensive relative to the cost of the kit (~$80 for the kit, ~$35 for replacement wires).I'd love to have more instructions printed on the device itself, especially for the "override" which unfortunately for me I have to use often.
